How to Use the TollGuru MCP in Mastra AI

Q: How do I manage trip cost calculations with TollGuru using Mastra AI?

You define a workflow that triggers calculatetollroute. If the initial calculation fails for any reason, Mastra AI's built-in retry logic will automatically try again until it successfully returns the full toll and fuel breakdown.

Q: Can I calculate multi-stop routes using TollGuru with Mastra AI?

Yes. Use calculatetollmultistop. You can build a workflow that takes dozens of waypoints, calculates the total cost at every plaza, and even triggers a notification if the resulting toll exceeds a set budget limit.

Q: Does TollGuru handle all vehicle types with Mastra AI?

It does. The calculatetollroute tool supports 2-axle cars, EVs, and large commercial trucks (up to 9+ axles). Your workflow can dynamically pass the correct vehicle type parameter for accurate cost estimates.

Perplexity

Automate multi-stop route budgeting.

The `calculate_toll_multi_stop` tool provides a detailed cost breakdown for routes that hit several waypoints. You can build a workflow using Mastra AI that takes an initial delivery list, calculates the optimal path and total tolls, and even suggests reordering stops to save money. Since Mastra AI handles automatic retries with exponential backoff, your complex logistics plan won't fail just because one endpoint is temporarily down. It keeps running until it finds a working cost estimate.

Execute full trip cost analysis reliably.

Use `calculate_toll_route` to build the core of your planning workflow. This tool calculates total costs, including tolls, fuel based on efficiency, and optional driver time. You can let Mastra AI handle requesting optimization—for instance, 'Find the cheapest route from LA to SF'—and it will manage the necessary API calls. Because you need reliable execution for these financial calculations, Mastra AI’s built-in workflow engine ensures that if a currency conversion fails or an endpoint times out, your job retries automatically.

Process existing GPS routes in workflows.

When the user already has a polyline from another mapping service, use `calculate_toll_from_polyline`. Mastra AI can incorporate this as a step: 1) Receive polyline data, 2) Send it to TollGuru for cost analysis, 3) Log the result. The tool returns all necessary toll and fuel details without requiring re-routing. This makes it perfect for multi-step processes where you need to validate costs based on external data sources.

Setup guide

Set up TollGuru MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All TollGuru tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "tollguru-mcp-client",
  servers: {
    "tollguru-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "TollGuru Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to TollGuru tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent TollGuru transactions"
);
console.log(result.text);

Common questions about TollGuru MCP in Mastra AI

You define a workflow that triggers `calculate_toll_route`. If the initial calculation fails for any reason, Mastra AI's built-in retry logic will automatically try again until it successfully returns the full toll and fuel breakdown.

The server processes route geometry (polylines), vehicle specifications, origin/destination points, and currency requests. The output is a structured set of cost metrics: tolls, fuel costs, and driver time estimates.

Yes. Use `calculate_toll_multi_stop`. You can build a workflow that takes dozens of waypoints, calculates the total cost at every plaza, and even triggers a notification if the resulting toll exceeds a set budget limit.

It does. The `calculate_toll_route` tool supports 2-axle cars, EVs, and large commercial trucks (up to 9+ axles). Your workflow can dynamically pass the correct vehicle type parameter for accurate cost estimates.

Definitely. The combination of TollGuru's detailed route data and Mastra AI's conditional branching means you can build logic like: 'If the toll cost is over $50, then notify an admin; otherwise, proceed.' This makes your operations highly resilient.
